You only put in 1/8 tank of 100/101? Damn...Greg told me it might be weird mixing the two gases, but I guess it works for you. I was going to do 50/50 daily and hope to run 16-17 pounds, but wasn't sure if the gas was able to mix properly in the tank before it got to the injectors. So for now I'm crappy 91 and turned down boost.
